'Shake up some music' - David Boyce
Interesting design with multiple removable speakers which operate wirelessly from an iPod base docking station which also charges the speaker units.
Each speaker is controlled by a range of gestures which enable the user to control the iPod and changing song volume etc.

The idea of having one main base station with multiple control modules could come in useful within a music therapy scenario as opposed to having a range of instruments.
